Does anyone know of this instructor

Years ago when I was in Waco TX 85-87 I worked out with an instructor named George Brock. I spoke with a friend of mine the other night and he told me he ran into him and he thought the guy was teaching Balintawak. I seem to remember several years back (mid 90's) seeing him at his school and I seem to remember something about him saying he was learning Balintawak and I think it was from GM Bobby Toboada?

My friend said he is still in Waco, and I thought I would maybe try and look him up sometime when I get down that way.

Just wondering if anyone has every heard, seen or know him? I mean no disrespect here to anyone, I was just wondering if anyone knows him.
